Frequently Asked Questions

Why does my Ring sensor keep showing tampered even after I fixed it?
This usually happens when the magnetic alignment is still slightly off or there's debris interfering with the contacts. Double-check that the sensor and magnet are within 1-2 inches of each other and clean both surfaces thoroughly.
Can a low battery cause a Ring sensor tamper alert?
Yes, low battery levels can cause erratic sensor behavior including false tamper alerts. Check your battery level in the Ring app and replace if it's below 20%.
How do I know which Ring sensor is tampered?
Open the Ring app and check the alarm history or device status section. The app will specifically identify which sensor triggered the tamper alert by name and location.
Will a Ring tamper alert trigger the full alarm?
Ring tamper alerts typically send notifications but don't trigger the full burglar alarm. However, this depends on your specific alarm settings and monitoring plan.
How often should I clean my Ring sensors to prevent tamper alerts?
Clean your Ring sensors every 3-6 months or whenever you notice dust buildup. Regular cleaning prevents debris from interfering with magnetic contacts and reduces false alerts.
